Brenda had bowling scores of 92, 110, 85, 78, and 96. She completed the steps below to determine the score she needs in her next

Simora [160]

Answer:

The mistake is evidently in the addition of the first 5 bowling scores

Step-by-step explanation:

Brenda had bowling scores 92, 110, 85, 78, and 96.

She needs one more bowl to get an average of 96.

Let the last bowl score = x

(92 + 110 + 85 + 78 + 96 + x)/6 = 96

(92 + 110 + 85 + 78 + 96 + x) = 96×6 = 576

461 + x = 576

x = 576 - 461 = 115

The mistake is evidently in the addition of the first 5 bowling scores, the score for the 5th bowl was excluded, maybe because it was coincidentally 96 too.

She added (92 + 110 + 85 + 78) instead of (92 + 110 + 85 + 78 + 96), so, the score needed for the last bowl to get an average of 96 is actually 115, not 211.

Hope this Helps!!!
